15 Claims. (Cl. 62-344) The present invention relates to ice cube ejectors, and is particularly concerned with ice cube ejectors of the .type adapted to loosen the ice cubes in a tray having a grid for shaping the cubes and also adapted to discharge the cubes into a storage container where they can be stored in a dry, cold condition without adhering to each other.

One of the objects of the invention is the provision of an improved ice cube ejector of the type adapted to be used with a flexible metal tray and a flexible non-metallic grid, all of the parts which taper toward their top edges, for twisting the tray and grid in the inverted position with the cubes in place, to break the bond between the cubes and the grid and the tray and to cause the cubes to drop into a storage container.

Another object of the invention is the provision of an improved ice cube ejector arrangement by means of which ice cubes may be removed without heating from the flexible tray having a flexible grid by inverting the tray and inserting it into a suitable support, and then cause the tray to be twisted by rotating a crank having a cam which acts on one corner of the tray to lift that corner of the tray while the rest of the tray is mounted at one end and secured against movement which necessitates the twisting by the action of the cam on the other end. Another object of the invention is the provision of an improved ice cube ejector for ejecting cubes from an inverted flexible ice tray and grid which not only twists the tray between its ends to break the bond, but it also permits the tray to snap back to the plane position, the snap back causing the cubes to be forcibly ejected in case they are not already sufliciently loosened.

Another object of the invention is the provision of an improved ice cube ejector for flexible trays and flexible grids of the type having a laterally projecting flange at the upper edge of the tray, by providinga pair of parallel guides for receiving this flange and holding the tray substantially against movement at one end while the other end of one is acted on by a cam which lifts one corner of the tray and guide assembly warping or twisting the tray and breaking the bond between the cubes and all States Patent, F

parts of the grid and tray, and thereafter permit the guide I improved mechanism for ejecting ice cubes from flexible trays which includes a suitable housing, upper and lower guides for engaging the bottom of the tray and for bolding one end in fixed position and a suitable pivot pin and bearing at one of the other corners of the tray, and a cam for acting on the opposite corner of the tray, whereby the tray is twisted upon its supporting rails, and the ice cubes are loosened and ejected.

Another object of the invention is the provision of .a plurality of forms of ice cube ejectors which are simple in construction, which include a minimum number of parts, which may be manufactured economically, which operate 2,934,916 Patented May 3, 196!) ICQ positively, and which not only loosen the ice cubes, but which eject them forcibly. e

Other objects and advantages of the invention will be apparent from the following disclosure and description, in which similar characters of reference indicate similar parts throughout the several views.

Referring to the three sheets of drawings,

Fig. 1 is a view in perspective showing an ice ejector embodying the invention, mounted in a suitable housing having an ice cube storage container;

Fig. 2 is a fragmentary view in perspective of the actuating lever for an ice cube ejector of the type in Fig. 1;

Fig. 3 is a view in perspective and in partial section of a flexible ice tray and flexible grid of the type preferably employed with this ice cube ejector;

Fig. 4 is a view in perspective of another modified form of ice cube ejectors;

Fig. 5 is a fragmentary view in perspective of the rear.

end of the tray showing the changes in construction that are involved in using the ejector of Fig. 4. The present ice cube ejector will preferably be employed with an ice cube tray and tapered grid assembly of the type shown in Fig. 3.

The tray and grid assembly of Fig. 3 is indicated in its entirety by the number 10 and preferably includes the tray 11 and the grid 12.

The tray is preferably a flexible metal tray which is only flexible because of the thinness of its walls and the material of which they are made, which is preferably aluminum. Thus, the tray has side walls 13, 14 and end walls 15, 16 all rectangularly joined to a bottom Wall 17.

The tray may take many different forms, but is preferably rectangular in form for the purpose of utilizing all the space in the box-like evaporators in which such trays are cooled.

The side walls 1316 are preferably provided with an outwardlyprojecting, upper border flange 18 for the purpose of strengthening the tray and for cooperation with the ejecting mechanism. Border flange 18 may be curled downward, if desired, for ornament, strength and engagement with the fingers. All of the side walls 1316 preferably slant outward, so that ice cube assembly will be larger at the top and smaller at the bottom of the tray, facilitating the withdrawal of the ice cubes.

The tray is preferably made of aluminum, but may also be made of flexible rubber or molded plastics. The rubber or plastic compositions may include powdered aluminum to increase their conductivity, which is one of the advantages of a metal or aluminum tray.

The grid 12 preferably includes a multiplicity of transversely extending webs 19 which are in the shape of upwardly tapering wedges, each web being narrow at the top edge 20 and wide at the bottom edge 21.

The webs are also provided with slots 22 extending into their lower edges in position to receive the divider strip 23. Since the divider strips are also wedge shaped, the slots 22 must be as wide as the widest part or bottom of each divider strip, and the slots 22 extend only part way into each web 19.

Thegrid is preferably provided with one or more divider strips 23 also made of flexible material and tapered from bottom to toplike the webs, so that the upper edge 24 of each divider strip is narrow and the bottom 25 of each divider strip is wide like a wedge.

The divider strips are provided with slots 26, extending into their upper edges at regularly spaced points along the length for receiving the webs. The width of the slots 26 must be sufficient to receive the thickness of the'web at the base of each slot 26.

The webs and dividers are assembled together to form the grid ,12 having a multiplicity of rectangular ice cube pockets and the top edges 20 and 24 of the webs and dividers are preferably flush with each other, but the webs may be wider at their lateral edges 27 and tapered downwardly at 28 to a narrower central portion. This permits the water to run from one pocket to another at the top of the tray, above the grid, so that all pockets will be uniformly filled. Any excess of water above the grid does not prevent the breaking up of the ice into cubes because ice is scored deeply from bottom almost to the top by the grids.

The grid may comprise separate thin dividers and webs, loosely slotted and secured in the tray so that the grid is flexible because of the clearance between its parts, permitting relativemovement and breaking the ice cubes loose from the grid.

' The grid may be flexible or movable because it comprises separate, rigid member's loosely connected by slots, or the grid may be molded out of t e integral piece of flexible material, such as, rubber or flexible plastic and when so shaped, all of the cubes will taper toward the bottom on all sides. i a

Referring to Fig. 1, this is a view showing the housing 29 for the ejector which may consist of an upper tray container 30 and a lower ice cube storage container 31 Each of these containers may consist of a stamped, sheet metal housing of rectangular shape in plan and elevation, and the end walls may be separately formed and riveted to the side walls.

The end walls and side walls each have the laterally projecting border flanges 32, 33 for attachment together to complete the housing by means of screw bolts. The storage bin 31 may be made deeper to store a large hum ber of cubes while the tray housing 30 need only .be large enough to receive the tray and its ejector mechanism.

Referring to Fig. 2, the ejector mechanism preferably includes border frame 34 of metal having attaching flanges 35, 36 for receiving screw bolts 27 to secure the frame in the housing.

Frame 34 has a rectangular aperture 38 which is large where it is pivotally mounted upon a bearing bracket 60, having a bearing aperture 61 and attached to the side wall of the housing by a flange 62 by bolts or rivets.

Bearing bracket 60 must be of sufficient length laterally to provide a clearance for the cam 63 which would otherwise engage the housing. 7

At its end, shaft 55 carries cam 63 which has a cylindrical portion 64 and a flat dwell 65 of minimum radius, against which the lever 44 rests in the position of Fig. 2. From the point 66, the cam gradually increases in radius until it has its maximum radius at the point 67 where there is an abrupt drop 68 on the cam. The operation of mechanism is as follows.

The tray of the type shown in Fig. 3 with the ice cubes frozen in it and bonded to the tray and the grid is inserted upside down with its border flanges in the slots 41, 42.

The tray having been fully inserted, the cam shaft 55 is rotated by the crank .56 and handle 59. This causes the cam 63 to rotate under the lever 44 until the rise 66 on the cam engages the lever and the right rear corner of the tray and guide 40 are lifted while the front ends of the tray and guides are held against twisting. During this motion, the lever 44 may pivot at 47, but the guides 39, 40 are sufficiently resilient to be twisted and bent, if necessary, within their elastic limit.

The twisting or warping of one corner of the ice tray upwardly causes all of the parts of the tray and guide to be warped and to slide relative to the ice surfaces of the cubes and the bond between the ice and rubber or metal is broken.

'As the rotation of the cam 63 progresses the abrupt drop 68 on the cam comes into position below the end enough to receive and pass an ice tray of the type'described, in inverted position. The frame 34 preferably supports a pair of elongated tray guides 39, 40 comprising bars of resilient metal, each of which is provided with inwardly facing, rectangular slots 41, 42. i

" The'slots 41, 42 are wide enough and deep enough to receive the border flange 18 of the tray and the guides are spaced sufficiently so that the tray with its border flange slides into the guides 41, 42 in'inver ted position.

At their front end, the guides 39, 40 may be welded or rigidly mounted on frame 34, or they may be provided with a pivot pin connecting them to the frame 34 as indicated at 43. I

At their rear ends, the guides 39, 40 may be pivotally or rigidly secured to the cam follower lever 44, which has upwardly extending lugs 45, 46 to which the guides are secured in spaced relation to receive the tray between them.

The cam follower lever is pivotally mounted by means of a pin 47 on a pivot bracket 48 which has a supporting base 49, secured by rivets or bolts 50 to the inside of the housing. The guides 39, 40 are preferably as long, or longer than the tray. Y

The lever 44 is urged in a clockwise direction by means of a coil spring 51, having one end hooked in an aperture 52, and having the other end hooked in an aperture 53, carried by the side wall ofthe housing 29.

The front frame 34 is preferably provided with a cylindrical bearing aperture 54 for receiving a cam shaft 55 which is provided on its front end with a crank 56. Crank 56 has an aperture 57 for the shaft to which it is pinned by pin 58. The crank may have a cylindrical handle 59. The crank preferably extends horizontally when the mechanism is at rest in the position of Fig. 2.

(Sam shaft 55 extends to the rear end of the assembly of lever 44. Lever 44 and the rear end of guide 40 snap down to the flat dwell 65 and to the parallel and coplanar position. The warping of the tray and guide has loosened the ice cubes and the snap back causes the tray and guide to eject the ice cubes into the ice cube storage bin 31.

Referring to Figs. 4 and 5, these views show a modification in which the ice tray rests upon a U-shaped frame 67, carried by the side walls of the housing previously described, and comprising a border flange member 68 and a pair of side frame members 69, 70.

The side frame members may each include a base rail "71 upon which the ice tray border flange rests in inverted position and an upwardly extending flange 72 for con: fining the tray against lateral movement. The housing also carries an upper transverse guide or frame member 73 which engages the bottom of the ice tray and prevents it from twisting at its forward end.

At its rear end the guide 69;. carries an upwardly projecting lug 74 with a bearing aperture 75 for receiving a pivot pin 76 which projects longitudinally from the rear wall 77 of the ice tray 78.

The guide rail 70 preferably carries a bearing bracket 79 at its rear end with an aperture 80 serving as a bearing for the cam shaft 81. Cam shaft 81 carries a cam 82 with a dwell 83 of minimum radius and a rise to the point 84 of maximum radius. The cam shaft projects toward an aperture 85 in the front frame member 67 and is provided with the same crank 86.

' In addition to the pivot pin 76 which is located toward the rear bottom corner of the tray, tray 78 also carries a rigid pin 87 upon which is rotatably mounted a sleeve 88 serving as a cam follower located to be engaged by the dwell 83 of the. cam.

The operation in this case is substantially the same, except that the tray is held against twisting at its front end by the rails 69, 70 and the upper guide 73.

As the crank 86 is rotated, cam 82 brings its edge into engagement with the follower 88 on the tray and as the radius increases that corner of the tray is lifted while the corner carrying pin 76 is permitted to pivot but is not lifted. This causes the tray to be warped which loosens all the ice cubes until the follower 88 7 drops off the rise 84 which permitsthe tray to snap back to a flat condition and ejects all of the ice cubes.

It will, thus, be observed that we have invented an improved ice cube ejector mechanism which requires only a minimum amount of labor on the part of the user. It is only necessary to take the tray with its ice cubes from the evaporator and invert it and place it in the ejector and then the crank is given one turn through 360'.

All of the ice cubes are immediately loosened and ejected into the ice cube bin without any heating or causing the cubes to become wet. In their dry, cold condition the cubes may be stored as long as necessary at a suitable temperature well below freezing so that they will not stick together.

While we have illustrated a preferred embodiment of our invention, many modifications may be made without departing from the spirit of the invention, and we do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of all changes within the scope of the appended claims.
